Execute DTS Package From A Stored Procedure?

When I run the code microsoft give to launch a DTS package from a stored procedure, the procedure runs continuously, never ending.

When I run the DTS package manually, or from a dtsrun utility, it only takes seconds.

I'm trying to automate this package so it will run after a field in a table has been updated.

Any suggestions are more than welcome.

PS. Here's the code I've been using (that doesn't seem to work):

--- Declare Variables
Declare @hr int
Declare @oPkg int

--- Create Package Object
Exec @hr = sp_OACreate 'DTS.Package', @oPkg OUT
If @hr <> 0
Begin
Print '*** Create Package Object Failed'
Exec sp_oageterrorinfo @oPkg, @hr
Return
End

--- Load Package
---DTSSQLStorageFlags :
---DTSSQLFlag_Default = 0
---DTSSQLStgFlag_UseTrustedConnection = 256

Exec @hr = sp_OAMEthod @oPkg,'LoadFromSqlServer("JENNSERVER", "", "", 256, , , , "RunMS")',null
If @hr <> 0
Begin
Print '*** Load Package Failed'
Exec sp_oageterrorinfo @oPkg, @hr
Return
End

--- Execute Package
Exec @hr = sp_OAMethod @oPkg, 'Execute'
If @hr <> 0
Begin
Print '*** Execute Failed'
Exec sp_oageterrorinfo @oPkg, @hr
Return
End

--- Clean Up Package
Exec @hr = sp_oadestroy @oPkg
If @hr <> 0
Begin
Print '*** Destroy Package Failed'
Exec sp_oageterrorinfo @oPkg, @hr
Return
End
